The patches are ready and I've just sent two for integration (one you
responded to), other three (return value predictors, dom updating fixes
and the overall switch to tree predictors) are in testing and
benchmarking now.  I understand that it is 14th intead of 5th, so if you
want to postnote the project, I won't complain strongly.
My understanding was that projects needs to be done till 29th so I
looked into some of bugfixes and compilation speed/memory issues in
meantime too (since the mainline got into somewhat unstable state) that
somewhat delayed me.
